CMOS Bus Controller
Features
The Intersil 82C88 is a high performance CMOS Bus
Controller manufactured using a self-aligned silicon gate
CMOS process (Scaled SAJI IV). The 82C88 provides the
control and command timing signals for 80C86, 80C88,
8086, 8088, 8089, 80186, and 80188 based systems. The
high output drive capability of the 82C88 eliminates the need
for additional bus drivers.
• Compatible with Bipolar 8288
Static CMOS circuit design insures low operating power. The
Intersil advanced SAJI process results in performance equal
to or greater than existing equivalent products at a significant
power savings.
• Provides Advanced Commands for Multi-Master Busses

STATUS INPUT PINS: These pins are the input pins from the 80C86, 80C88,8086/88, 8089 processors. The
82C88 decodes these inputs to generate command and control signals at the appropriate time. When Status pins
are not in use (passive), command outputs are held HIGH (See Table1).
CLK

I
CLOCK: This is a CMOS compatible input which receives a clock signal from the 82C84A or 82C85 clock
generator and serves to establish when command/control signals are generated.
ALE

O
ADDRESS LATCH ENABLE: This signal serves to strobe an address into the address latches. This signal is
active HIGH and latching occurs on the falling (HIGH to LOW) transition. ALE is intended for use with transparent
D type latches, such as the 82C82 and 82C83H.

I
ADDRESS ENABLE: AEN enables command outputs of the 82C88 Bus Controller a minimum of 110ns (250ns
maximum) after it becomes active (LOW). AEN going inactive immediately three-states the command output
drivers. AEN does not affect the I/O command lines if the 82C88 is in the I/O Bus mode (IOB tied HIGH).

INPUT/OUTPUT BUS MODE: When the IOB pin is strapped HIGH, the 82C88 functions in the I/O Bus mode.

MCE/PDEN

O
This is a dual function pin. MCE (IOB IS TIED LOW) Master Cascade Enable occurs during an interrupt sequence
and serves to read a Cascade Address from a master 82C59A Priority Interrupt Controller onto the data bus. The
MCE signal is active HIGH. PDEN (IOB IS TIED HIGH): Peripheral Data Enable enables the data bus transceiver
for the I/O bus that DEN performs for the system bus. PDEN is active LOW.
Functional Description
The command logic decodes the three 80C86, 8086, 80C88,
8088, 80186, 80188 or 8089 status lines (S0, S1, S2) to
determine what command is to be issued (see Table 1).

IOB mode if I/O or peripherals dedicated to one processor
exist in a multi-processor system.
System Bus Mode
The 82C88 is in the System Bus mode if the IOB pin is
strapped LOW. In this mode, no command is issued until a
specified time period after the AEN line is activated (LOW).
This mode assumes bus arbitration logic will inform the bus
controller (on the AEN line) when the bus is free for use.
Both memory and I/O commands wait for bus arbitration.
This mode is used when only one bus exists. Here, both I/O
and memory are shared by more than one processor.
Command Outputs
I/O Bus Mode
The 82C88 is in the I/O Bus mode if the IOB pin is strapped
HIGH. In the I/O Bus mode, all I/O command lines IORC,
IOWC, AIOWC, INTA) are always enabled (i.e., not
dependent on AEN). When an I/O command is initiated by
the processor, the 82C88 immediately activates the
command lines using PDEN and DT/R to control the I/O bus
transceiver. The I/O command lines should not be used to
control the system bus in this configuration because no
arbitration is present. This mode allows one 82C88 Bus
Controller to handle two external busses. No waiting is
involved when the CPU wants to gain access to the I/O bus.
Normal memory access requires a “Bus Ready” signal (AEN
LOW) before it will proceed. It is advantageous to use the
3
The advanced write commands are made available to initiate
write procedures early in the machine cycle. This signal can
be used to prevent the processor from entering an
unnecessary wait state.
INTA (Interrupt Acknowledge) acts as an I/O read during an
interrupt cycle. Its purpose is to inform an interrupting device
that its interrupt is being acknowledged and that it should
place vectoring information onto the data bus.
The command outputs are:
MRDC - Memory Read Command
MWTC - Memory Write Command
IORC - I/O Read Command
IOWC - I/O Write Command
AMWC - Advanced Memory Write Command
AIOWC - Advanced I/O Write Command
INTA - Interrupt Acknowledge

82C88
Control Outputs
Address Latch Enable and Halt
The control outputs of the 82C88 are Data Enable (DEN),
Data Transmit/Receive (DT/R) and Master Cascade Enable/
Peripheral Data Enable (MCE/PDEN). The DEN signal
determines when the external bus should be enabled onto
the local bus and the DT/R determines the direction of data
transfer. These two signals usually go to the chip select and
direction pins of a transceiver.
Address Latch Enable (ALE) occurs during each machine
cycle and serves to strobe the current address into the
82C82/82C83H address latches. ALE also serves to strobe
the status (S0, S1, S2) into a latch for halt state decoding.
The MCE/PDEN pin changes function with the two modes of
the 82C88. When the 82C88 is in the IOB mode (IOB HIGH),
the PDEN signal serves as a dedicated data enable signal
for the I/O or Peripheral System bus.
Interrupt Acknowledge and MCE
Command Enable
The Command Enable (CEN) input acts as a command
qualifier for the 82C88. If the CEN pin is high, the 82C88
functions normally. If the CEN pin is pulled LOW, all
command lines are held in their inactive state (not threestate). This feature can be used to implement memory
partitioning and to eliminate address conflicts between
system bus devices and resident bus devices.
The MCE signal is used during an interrupt acknowledge
cycle if the 82C88 is in the System Bus mode (IOB LOW).
During any interrupt sequence, there are two interrupt
acknowledge cycles that occur back to back. During the first
interrupt cycle no data or address transfers take place. Logic
should be provided to mask off MCE during this cycle. Just
before the second cycle begins the MCE signal gates a
master Priority Interrupt Controller’s (PIC) cascade address
onto the processor’s local bus where ALE (Address Latch
Enable) strobes it into the address latches. On the leading
edge of the second interrupt cycle, the addressed slave PIC
gates an interrupt vector onto the system data bus where it is
read by the processor.
If the system contains only one PIC, the MCE signal is not
used. In this case, the second Interrupt Acknowledge signal
gates the interrupt vector onto the processor bus.

1. Address/Data Bus is shown only for reference purposes.
2. Leading edge of ALE and MCE is determined by the falling edge of CLK or status going active. Whichever occurs last.
3. All timing measurements are made at 1.5V unless otherwise specified.
